In clear the game can be considered as clean, but TrueCombat Elite is an hard game, so you need to practice a lot before being able to do same as strongest players. Some glitch/bugs may confuse some people too.

Also keep in mind that most of clan-members play connected on TeamSpeak servers, so they might get a better teamplay (if you don't have a TeamSpeak server, Skype might be an alternative with friends).

Begin with BodyCount (kill + respawn) servers in order to get to know the maps, locations and gameplay, then go on some Objective(Plant/Defuse bomb + only 1 life for a round)servers in order to experience the original design of the game.
